Classifies clichés in storytelling.
Every page is highly intelligent and interlinked to other pages.
It is incredible.

Ciro Santilli publishes videos of this not-so-common visual programming experiments on his YouTube channel occasionally: www.youtube.com/c/CiroSantilli. Ciro should however not be lazy and also upload each video produced to Wikimedia Commons, since YouTube does not offer a download option even for videos marked with a Creative Commons license: www.quora.com/Can-I-download-Creative-Commons-licensed-YouTube-videos-to-edit-them-and-use-them/answer/Tarmo-Toikkanen!
This is also where Ciro's downtime converged to in his early 30's, since he long lost patience for stupid video games and television series.
Ciro developed one interesting technique: while scrolling through YouTube's useless recommendations, when he understands what a channel is about, he either immediately:
  • subscribes if it is amazing and then "Don't recommend channel"
  • otherwise just "Don't recommend channel" immediately
This helps to keep this feed clean of boring stuff he already knows about. There is unfortunately an infinite amount of useless videos out there however on the topics of:
and no matter how much you say you don't want to hear about them, YouTube juts keeps on sending more.
Things Ciro hates about YouTube:
  • you can't follow or ignore a subject, only indirectly tell the algorithm about that. Once you click a popular cat video, you will be forced to watch cat videos for all eternity.

Other super important ones:
The principal quantum number thing fully determining energy is only true for the hydrogen emission spectrum for which we can solve the Schrödinger equation explicitly.
For other atoms with more than one electron, the orbital names are just a very good approximation/perturbation, as we don't have an explicit solution. And the internal electrons do change energy levels.
Note however that due to the more complex effect of the Lamb shift from QED, there is actually a very small 2p/2s shift even in hydrogen.
